FILM FOB MOVING-PICTURE MACHINES,

Specification of Letters Patent.

Application filed October 25,1909. Serial No. 524,365.

To all who'in it may concern:

Be it known that I, GEORGE W.'BINo1rAM,

gle row. This strip of film is drawn through the machine and in the winding and rewinding thereof, it is subjected to a great deal of wear and tear.- The film is also more or less bulky and unwieldy, it is liable. to be come torn and it is open to numerous other objections.

'My invention has for its object, to overcome the various disadvantages which are incidental to the strip form of film.

M .invention therefore consists broadly in pacing the pictures upon the film in a series of rows arranged side by side. The

. the machine.

film is then carried through the moving 'picture machine with an intermittent mot-ion in such manner as to bring the individual pictures of the difi'erent rows, successively into alinement with the exposure opening of By moving picture machine I mean eitherthe camera for taking the )ictures, or the projecting apparatus for exhi iting the same. With the film in strip form, the ictures in the single row have to be individua ly printed'one after another. This is an expensive and troublesome process.

Another object of my invention is to accomplish the printing of the pictures on the film, simultaneously.

,The film may be either a flexible sensitized surface, or a plate of glass, celluloid or like material, and the term film will be understood to mean either the positive which is used with the projector, or the negative which is run through the camera, The Same meaning attaches to the use of the Word pictures On the'positive, the plcture will be actually apparent, while obviously, on the negative, the so-called pictures will consist merely of a continuous sensitized surface adapted to receive the impressions.

In the preferred form of the invention, the film is in the shape of a round plate or disk and the pictures are disposed spirally thereon, ranging progressively from the center to the rim of the disk.

Various otherfeatures of the invention will appear as the specification proceeds. In the accompanying drawings there are illustrated several preferred forms of the in vention, but various modifications .and changes may be made therein without de parting from the spirit and scope of' the invention.

In the drawings is illustrated a plan or face view'of the preferred form of the invention wherein the film is in the shape of a disk and the pictures are arranged in spiral rows thereon.

The film as shown preferably consists of a disk 1, of celluloid or like material which is provided with a sensitized surface to receive the impressions or pictures 2 on its face. The successive pictures are arranged in rows, as'shown, and these rows are disposed in spiral relation, ranging from the center to the periphery of the disk, as. illustrated.

-An intermittent shifting motion is imparted to the film by any suitable mechanism' (such as that shown in my Patent No. 971,588 granted Oct. 4;, 1910) so as to bring the pictures successively into alinement with the exposure opening of the machine, and a certain lateral shifting motion must also be given to the film so as to bring the different rows into register with the opening. The film shown in the drawing is given an intermittent spiral movement to bring the-pictures successively into alinement with the exposure opening. The series of pictures may start either at the center or at the edge of the disk, and the direction of movement would of course correspond.

The pictures may be placed very close together on the filmv so that the film while compact in size has a comparatively. great capacity for exhibition purposes. Furthermore, by arrangingthe pictures in rows on the same film, I am enabled to print allthe Patented N ov. 26, 1912..

stationary in the placed just preceding the first pictures at the same time, with the same case and facility as in printing a single picture.

In order to protect the edge of the film from injury, I may apply a binding strip 8 to the edge thereof. This binding strip may he of metal, such as aluminum, or it may be a fabric of some sort. This binding strip lends a certain rigidity to the film itself, thereby permitting the film to be made of a comparatively light and thin material.

The light and heat generated by the projecting apparatus is very intense and in some cases it is sufliciently'strong to set fire to the film if the film is allowed to remain rojector for any length of time when the light is on. In order to obviate any danger of this sort, I prefer to provide the film with one or more openings 9, sufficiently large to permit unobstructed passage of the light rays therethrough. One of these openings would preferably be of the series of the pictures on the film and if found de- 'sirable, a light opening could be placed at the end of the series, or at points intermediate. The film may. thus be placed in the projector and allowed to remain there, with the lightturned on, until ready for use. The light opening at the beginning of the pictures is also of assistance in initially posit-ioning the film with respect to the expo sure opening of the machine.

I claim:

1. A film for moving picture machines comprising a sheet of celluloid or like ma terial provided with a series of progressively disposed pictures thereon, there heing provided an opening in the sheet of material preceding the first of the series of pic tures and said opening being of a size as large or larger than the pictures so as to permit the-free passage of the beam of light emanating from the projection apparatus of the machine.

2. A film for moving picture machines comprising a disk of celluloid or like transparentmaterial provided with a series of pictures arranged progressively thereon said disk having an opening therein located in advance of the series of pictures and said opening being large enough to permit free passage of the beam of light emanating from the projection apparatus of the machine.

Signed at New York in the county of New York and State of New York this 22nd day of October A. D. 1909.
